Abstract: 1,062,505. Catalytic heat-exchange reactors. LUMMUS CO. Oct. 7, 1965 [Oct. 12, 1964], No. 42600/65. Headings B1F and B1X. A gas-phase catalytic reactor for exothermic reactions comprises within a common shell a heat exchanger above which is in succession, a plurality of catalyst beds fed in parallel by a corresponding number of gas streams from the heat exchanger. In Fig. 5, the gas mixture enters external shell 10' at 12' and passes down the space between 10' and inner shell 30' before entering heat exchanger 25' at the bottom. From heat-exchanger 25', which is divided into two by partition 26', the gas mixture passes by duct 36' to the top of catalyst bed 68 and by duct 38' to the top of catalyst bed 14. Into these beds quenching gases may be passed by ducts 130- 133. Reacted gases leave the catalyst beds by the bottom and pass by header 84' to the pipes by which they are conveyed through heat exchanger 26' to header 86' and exit 64'. In a modification (Fig. 1, not shown), further heat exchange is provided for by passing the incoming gas mixture in ducts up through the catalyst beds before reaction, and conducting cooling gases into the top of the heat exchanger instead of directly into the catalyst beds. The reactor may be employed for ammonia synthesis at 400-600C.

Title: Methods of manufacturing webs comprising a plurality of serially interconnected plastics bags
IPC: B31B23/00
Filed: 1977-10-13
Abstract: The tubular web of film has a plurality of plastic bags which can be separated from this web of film. This provides the advantage that the plastic bags can be made available to the user in a coiled form. This form is very easy to use, in contrast to a stack of loose plastic bags. In this case, each plastic bag is provided with first corner fold welding seams (8, 9, 10, 11). Each of these welding seams connects an outer web of film (1a, 1b) in each case to the fold part (5, 5a, 6, 6a) located immediately below it and to second corner fold welding seams (13, 14, 15, 16). The first corner fold welding seams (8, 9, 10, 11) are connected to a plastic bag closure welding seam (12). When the web of film is produced, the corner fold welding seams are firstly produced from a tubular film and the closure welding seam (12) is produced subsequently. <IMAGE>

Title: Calculating apparatus to carry out arithmetical calculations
IPC: G06G1/12
Filed: 1959-12-16
Abstract: 881,480. Mechanical calculating-apparatus. MUIRHEAD, L. A. Dec.16, 1959, No. 42715/59. Class 106 (1). Calculating-apparatus has relatively movable members bearing linear and logarithmic scales for the performance of the four rules and interconnecting means to enable the transfer of the result of an addition and/or subtraction operation to the logarithmic part of the apparatus for use in a multiplication or division operation. The apparatus described is for calculating motor vehicle fuel consumption between first and second mileages. A base 1 carries a disc 5 having a pivot movable along a slot 2 in the base. Mounted on the same pivot is a disc 11 with a linear scale 11a and carrying balls 6 bearing on the disc 5 and a disc 10 fixed to the base. The scale 11a is read against an index 12 non-rotatable relative to the base. The disc 5 is formed with a slot 13 in the shape of a logarithmic curve into which extends a wire 14 from a fixed opening in the base 1 Adjacent to the opening is a projection 16 of the base which engages in the slot 13. As the disc 5 is rotated, the point at which the wire enters the slot 13 changes and so the disc 5 is moved along its slot 2. The wire 14 extends in a slot 17 in the base and has its end secured at 18c to a disc 18 rotatable concentrically relative to the base 1 and bearing a logarithmic scale 18a readable against a fixed index 18b. The position of the free end of the wire 14 in the slot 13 of the disc 5 may be read against a scale 21 on that disc. With the disc 5 in its initial position relative to the base 1 as shown in Fig. 1, the dial 11  is set, without moving the disc 5, according to the first mileage. The dial 5 is then moved so as to drive the disc 11 (through the ball bearings 6 acting on the fixed disc 10) until the second mileage is indicated on the scale 11a. This rotation of the disc 5 thus corresponds to the distance travelled and the shape of the slot 13 is such that a length of wire 14 is withdrawn from the slot corresponding to the logarithm of that distance. The disc 18 is then set by the logarithmic scale 18a according to the number of gallons of fuel used and this movement feeds back into the slot 13 a length of wire corresponding to the logarithm of the quantity of fuel. The final position of the end of the wire in the slot 13 thus corresponds logarithmically to the fuel consumption in miles per gallon, which may be read against the scale 21.

Abstract: 1,162,988. Magnetic storage devices. WESTERN ELECTRIC CO. Inc. 30 Sept., 1966 [4 Oct., 1965], No. 43726/66. Heading H3B. Information is written into a selected thin film storage element in a word-organized matrix store by applying a preparatory word pulse +Iw, Fig. 2, which rotates the magnetic flux from the easy axis to a first direction along the hard axis, followed by the application of a second word pulse - aIw of opposite polarity as well as a coincident and overlapping digit pulse + Id or - Id the polarity of which is determined by the digit to be stored, the second word pulse rotating the magnetic flux from the first direction to the second direction along the hard axis, while the digit pulse tips the flux from the second direction towards one or other of the two possible directions along the easy axis according to its polarity. Non-destructive read-out is effected by applying a subsequent pulse Ir to the word line. It is stated that the flux switching process prevents flux components from relaxing in an inappropriate direction along the easy axis and so enhances the output signal obtained during read-out. A matrix store of conventional circuitry is described, Fig. 1 (not shown), the matrix comprising a glass substrate having a plurality of discrete deposited thin film spots, orthogonal word and digit conductors being arranged to overlie the spots and to complete return paths on the reverse face of the substrate.
